Double Replacement Reaction Definition. A double replacement reaction is a chemical reaction where two reactant ionic compounds exchange ions to form two new product compounds with the same ions. Double replacement reactions take the form: A+B- + C+D- â A+D- + C+B-. In this type of reaction, the positive-charged cations and the negative-charged anions of the reactants both trade places (double displacement), to form two new products. Also Known As: Other names for a double displacement reaction are a metathesis reaction or a double replacement reaction.
Cincinnati-based Kroger operates dozens of stores throughout Oregon, including 53 under the Fred Meyer brand that started in Portland. There are now 132 Fred Meyer stores now operate in four states -- Oregon, Washington, Alaska and Idaho. Kroger also has a half-dozen QFC stores in the Portland metro area. It's unclear, though, how many of the new jobs will be based in the Pacific Northwest. The entire Fred Meyer division in the four states will have 1,700 openings, spokesperson Amanda Ip said.
Menards, based in Eau Claire, Wisconsin, has nearly 300 stores in 14 states, so it has a long way to go to catch up with Lowe's (1,840 stores) and Home Depot (2,270 stores). For investors, though, the fate of Menards is only of concern as to how it might affect the stock price for Home Depot and Lowe's. If the chain grows, it's unlikely to cause a dent; if it shrinks, it could signal further dominance by it rivals.
